Their website indicates that if you miss raw or Smackdown you can watch it next day on Hulu. However, that’s not actually the case, and I’m pretty sure it’s been that way since Raw moved to Netflix in January. And as far as I can tell they’re is NO WHERE to watch Main Event in the States any more until a month later on Peacock. 
Saturday night main event is different from WWE Main Event (the weekly, we’ll it used to be the C show but it’s probly like the K show by now)
Oops, I totally missed that detail. I went and checked Main Event for real this time and I seem to be able to watch everything including the May 22 show, on Peacock.
